Summary:Generally, detection and diagnosis of incipient faults are desirable in order to ensure product quality and improved operational efficiency of induction motors running off the mains power supply. In this paper, the vibration and current spectrum of an induction motor are analyzed in order to achieve information for the detection of rotor bars faults. We observe significant vibration and current spectrum differences between healthy motors and motors with broken rotor bars. The high-frequency spectral analysis of vibration and current provides a method to detect broken rotor bars faults. The developed system is scalable to power ratings and it has been successfully demonstrated with data from 0.65 kW single phase induction motor.
